From Chapter 3:
Penalties for "offences" of this fanciful kind were not common in England; but in Puritan New England they were abundant. In the early days of the American Colonies the use of the "creature called Tobacko" was by no means encouraged. In Connecticut a man was permitted by the law to smoke once if he went on a journey of ten miles, but not more than once a day and by no means in another man's house. It could hardly have been difficult to evade so absurd a regulation as this.

From Chapter 8:
Cowper's aversion from tobacco could not have been very strong, for he encouraged his friend to smoke in the famous Summer House at Olney, which was the poet's outdoor study. Bull smoked Orinoco tobacco, which he carried in one of the tobacco-boxes, which in those days were much more commonly used than pouches, and this box on one occasion he accidentally left behind him at Olney. Cowper returned it to him with the well-known rhymed epistle dated June 22, 1782, and beginning:

If reading verse be your delight,
'Tis mine as much, or more, to write;
But what we would, so weak is man,
Lies oft remote from what we can.
